[no Bug] [SOLVED] NO Audio in TV after resume Powermode (2 Viewers)

[azzuro]

When my HTPC resume from PowerSleep, i have no audio when i look TV, i have not tested with myvidéo.

channel is France 2

TOPIC SOLVED POST
Soundcard Driver ( Realtek) not restart

Are you using the latest ATI driver? I think, you use v12.04 - please update to v12.06.

I think the ATI-Driver doesn't recognize the HDMI-Port of your TV - and at this point, HDMI-Out isn't available as default direct sound device. No device - No Sound!

(Please fill out SYSTEM-SPEC)

Another solution is to use the Realtek HDMI audio drivers and not the ones ATI provides. But I think CCC 12.6 solves this issue.
It is unlikely that this is a MediaPortal bug.. have you tested if sound works outside MediaPortal after resume? Maybe try VLC or Windows Media Player.
Thanks!

Hi,
i don't use HDMI, only S-VIDEO ( i know it's too old .... but my TV have 6 Years only !)
i think i have ATI 12.6.
i must try with an other software, but i have no sound directly after resume, no sound in menu, nothing !

in queue i must try :
- test resume without MP ( like VLC) ( with Windows / without Windows )
- Update Drivers


Problem is here ?

Hi.
Sounds as if your onboard soundcard did not awake after sleep.

Maybe you can solve this with "Hibernate Trigger", PS Tools and "Devcon" Here's an example for restarting TV card after standby

net stop tvservice
C:\PSTools\PSKILL -T tvservice.exe
C:\Devcon\devcon enable *14F1
C:\Devcon\wait 2
net start tvservice
exit

I didn't had those for Audio up to now so you need to fiddle a bit to get this adapted for your audio device.

 

[azzuro]

Yeah,
Before enter in TVmode, I have no sound in MP Menu when scrolling in Home, Tvservice can block soundcard ?

 

[Lehmden]

Hi.
Don't believe this. Above example is for restarting TV Card which is definitely blocked by TV Server.

In your case I believe the soundcard did simply not wake up after resume from standby (hibernate,... whatever)
So you have to do something like "devcon enable xxxxx" with the ID of your soundcard (look in device manager to get this). You can test it in command prompt after your sound is gone. If this works you can create a batch and auto execute this .bat with hibernate trigger....

BTW this is no MP problem, its an issue of your hardware... And this is a dirty workaround, but most of the time it works, so no need to trash your mainboard for this...

 

[azzuro]

Ok,
i will try ... i must know where is my prob, tvcard, MP, or system (soundcard)

Thx Lehmden

Hi, Lehmden
After search, my problem is soundcard Driver by Realtek !
i have reinstalled default driver from Microsoft, and work normally. Thx for your help !

For Test ( or for users with problem ) : line code of batch. only for Driver Problem

C:\Devcon\devcon restart *10EC
exit

"Enable" changed by "restart" because Device is loaded.

Batch for problem with Tvserver !

net stop tvservice
C:\PSTools\PSKILL -T tvservice.exe
C:\Devcon\devcon restart *10EC
choice /T 2 /D O
net start tvservice
exit

"wait" changed by "choice" wait is not default command in win7 but can be download here and paste it in c:\windows folder

SOLVED !​
